title: [Relation between dietary and physical activity patterns and obesity in seven year old children--current situation--WHO study].
abstract: BACKGROUND
  Childhood obesity is a global health problem. For monitoring of trends in obesity prevalence and comparison between countries standardized methods are necessary. WHO/Europe launched the "Childhood Obesity Surveillance Initiative" project in 2006 aiming to monitor childhood obesity and associated factors in European countries. This paper provides an overview of the situation in the Czech Republic with focus on diet and physical activity.
  
  
  RESULTS
  The cohort included 1704 seven-year olds who were examined by paediatricians in 2008 (essential anthropometric measurements). Questionnaires on children's eating habits, physical activity, family, and school environment were filled in. Statistical methods employed. Multivariate regression with reduction of dimensionality (bi-directional orthogonal projection to the latent structure), one-way ANOVA. Low-fat milk intake frequency was positively correlated with BMI (p = 0.0001), while full-fat milk intake was negatively correlated (p = 0.005). These results probably reflect the change in the diet due to increasing BMI. Number of preventive school programmes aimed on health promotion was negatively associated with BMI (p = 0.026).
  
  
  CONCLUSIONS
  Surprisingly, low-fat milk consumption was associated with higher BMI in seven years old children, while full-fat milk consumption was associated with lower BMI. School preventive programmes positively affect children's weight.
